what role do stents play in the treatment of myocardial infarctions?

by Howard Legros Published 2 years ago Updated 2 years ago

Cardiac stents are expandable coils made of metal mesh. Your doctor can insert one during a coronary angioplasty, a nonsurgical and minimally invasive procedure. The device is designed to support your artery walls, keep your artery open, and improve blood flow to your heart.

Primary percutaneous coronary intervention (PCI) with stent implantation has been the standard therapy in acute STEMI patients. Compared with medical treatment alone, stent implanting can achieve larger lumen gain and helps to reduce the re-occlusion risk of the infarct-related artery (IRA).

Full Answer

How are stents used to treat a heart attack?

They can also treat a heart attack that's in progress. To put a stent in, your doctor makes a small cut in a blood vessel in your groin, arm, or neck. They then thread a thin tube called a catheter through the blood vessel to the blocked artery. The tube has a tiny balloon at the end of it.

What is a a stent?

A stent is a tiny tube that can play a big role in treating your heart disease. It helps keep your arteries -- the blood vessels that carry blood from your heart to other parts of your body,...

What medications are given after a heart stent is placed?

After your stent placement, your doctor will prescribe medications, such as aspirin, clopidogrel (Plavix), ticagrelor (Brilinta) or prasugrel (Effient), to reduce the chance of blood clots forming on the stent.

How long does a stent stay in the artery?

The stent stays in the artery permanently to hold it open and improve blood flow to your heart. In some cases, more than one stent may be needed to open a blockage.

Are stents used for myocardial infarction?

Initial wariness about stent implantation in the thrombogenic milieu of AMI has rapidly faded away and stent-based primary PCI has been shown to be the superior method of reperfusion compared with thrombolytic therapy in terms of reducing death, re-infarction and stroke.

What is the function of heart stent?

A stent is a tiny, expandable metal mesh coil. It is put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Once the stent has been placed, tissue will start to coat the stent like a layer of skin.

How do stents help coronary heart disease?

A stent is a tiny tube that can play a big role in treating your heart disease. It helps keep your arteries -- the blood vessels that carry blood from your heart to other parts of your body, including the heart muscle itself -- open. Most stents are made out of wire mesh and are permanent. Some are made out of fabric.

Why are stents used after a heart attack?

In many cases, doctors insert a coronary artery stent after an angioplasty. The stent helps keep the blood flowing and the artery from narrowing again. Having an angioplasty within the first hours after a heart attack may reduce your risk of complications. Timing can be crucial.

What are the benefits of stents?

It can substantially improve your blood flow and prevent further damage to your heart muscle. It can also improve symptoms of heart disease, such as chest pain (angina) and shortness of breath. In many cases, you will feel the benefits immediately.

What are stents and what are they used to treat?

What do stents do? These tiny but vital devices can hold the artery open in an area where you have a narrowing. They are inserted in an angioplasty procedure, either as an emergency to treat a heart attack, or in a planned way to widen an artery that is being narrowed by a build-up of fatty plaque.

What are the pros and cons of a stent?

How many stents can you have in your heart at one time?

In answer to your first question, in some cases doctors can place two or even three stents during one procedure. There are, however, cases in which the cardiologist will want to place one and then place a second or even a third stent in a later procedure.

What percentage of artery blockage requires a stent?

“For a cardiac stent procedure to qualify as a medical necessity, it is generally accepted that a patient must have at least 70% blockage of an artery and symptoms of blockage,” Justice Department attorneys wrote.

Where do they place heart stents?

A coronary artery stent is a small, metal mesh tube that is placed inside a coronary artery to help keep the artery open. To place the stent, a small sheath, plastic tube, is placed in the groin or wrist artery. A catheter is guided through the artery into the part of the coronary artery that is blocked.

Can you still have a heart attack with a stent?

Many heart patients who have gone through stenting procedures have this doubt in their minds. So, without a long post to read, let us come straight to the answer that is, yes. You can get a heart attack again even after you have undergone a cardiac stenting procedure.

How long do stents last after a heart attack?

Stents are small tubes inserted into your body to reopen a narrowed artery. They are made to be permanent — once a stent is placed, it's there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.

Overview

Image
Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries. Angioplasty uses a tiny balloon catheter that is inserted in a blocked blood vessel to help widen it and improve blood flow to the heart. Angioplasty is often combined with the placeme…

Why It's Done

  • Angioplasty is used to treat the buildup of fatty plaques in the heart's blood vessels. This buildup is a type of heart disease known as atherosclerosis. Angioplasty may be a treatment option for you if: 1. You have tried medications or lifestyle changes but these have not improved your heart health. 2. You have chest pain (angina) that is worsening. 3. You have a heart attack. Angioplast…

Risks

  • Although angioplasty is a less invasive way to open clogged arteries than bypass surgery is, the procedure still carries some risks. The most common angioplasty risks include: 1. Re-narrowing of your artery.When angioplasty is combined with drug-eluting stent placement, there's a small risk the treated artery will become clogged again. The risk of re-narrowing of the artery is higher …

How You Prepare

  • Before a scheduled angioplasty, your doctor will review your medical history and do a physical exam. You may need to have some tests, including a chest X-ray, electrocardiogram and blood tests, before your procedure. Your doctor will also perform an imaging test called a coronary angiogram to see if the arteries to your heart are blocked and if they can be treated with angiopl…

What You Can Expect

  • During the procedure
    Angioplasty is performed by a heart specialist (cardiologist) and a team of specialized cardiovascular nurses and technicians in a special operating room called a cardiac catheterization laboratory. Angioplasty is performed through an artery in your groin, arm or wris…
  • After the procedure
    If you had a nonemergency procedure, you'll probably remain at the hospital overnight while your heart is monitored and your medications are adjusted. You generally should be able to return to work or your normal routine the week after angioplasty. When you return home, drink plenty of fl…

Results

  • Coronary angioplasty greatly increases blood flow through the previously narrowed or blocked coronary artery. Chest pain generally should decrease. You may be better able to exercise. Having angioplasty and stenting doesn't mean your heart disease goes away. You'll need to continue healthy lifestyle habits and take medications as prescribed by your doctor. If you have symptom…
